Arthroscopy, or arthroscopic surgery, can be used to diagnose and/ or treat ankle and foot problems using a less invasive procedure. During arthroscopy, the doctor makes tiny incisions at the site and inserts an arthroscope and tiny surgical instruments through the incisions. The arthroscope is a fiber-optic camera that allows the doctor to view and diagnose internal damage. The procedure makes it possible to view and assess the problem as well as perform surgical corrections, such as removing cartilage and repairing damaged joints and tissue. Arthroscopic surgery reduces trauma to surrounding tissue and cuts down on swelling, healing time, and the risk of infection. It is usually done as an outpatient procedure under local anesthesia.
